To 1310150972. it may concern:

Be it known that I, FREDERICK M. Foasra, a citizen of the United States, residing at Revere, in. the county of Suffolk and State of Massachusetts, have invented cnrtain In provcments in Methods of Applying Blacking to Boots or Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indi cating like parts in the several figures.

This invention relates to a method of applying blackingto boots and shoes and al.- though it is in no respect so limited, it iinds particular application to the blocking of heels with quick drying hlacking. For convenience of discussion, the term blacking will be used frequently in the specification and claims to include all sorts of similar finishing material, such as inks, colored stains, enamel of any desired color, etc. and the work will be referred to as the heel although the invention obviously has application to other parts of a boot or shoe.

Certain kinds of finish, of which White enamel is a notable example, have the chem acteristic of drying very quickly. Partly for this reason andpart y perhaps because they are composed largely of varnish, considerable difliculty is experienced in applvin this blackjng Without lcavin the marks 0, the bristles of the applying rush or of overlapping brush strokes. It has been customary, accordingly, to apply manually blackings of this sort with a single relative movement of the shoe and a soft camels hair brush. This operation, because of the necessity of getting the blacking into the rand crease without smoothing the upper, is

and expensive and great dliiiculty has been experienced in thereby thoroughly applying the blacking to the rand crease at the time that it is applied to the surface of the heel. Because of the quick drying quality of this class of blacking, it has been found inexpedient to make more than one application of blocking to the heel for the reason that overlapping strokes leave a noticeable ridge. Flirt ermore, any attempt to utilize the ordinary type of blacking machine having driven rushes with moderately stifl bristles almost invariably results in the production of brush marks. An objcctof the invention is to devise a method of blacking heels by means of which blanking may be successfully applied and the above mentioned and other diflicultics avoided.

According to the preferred practice of the invention, the blac ing is first applied to the rand crease and an adjacent pm'tion of the heel by a sin lc relative mowment of the work and 1a lacking applying means designed to furnish blackin to and open up the rand crease and prefeia ly to a narrow l5 portion of the surface of the heel or edge of the solo immediately adjacent thereto. Black-ingis then applied to the remainder of the surface of the heel in any desired manner as, for example, by a single stroke of a soft camels hair brush around the periphcry of the heel. This latter step of the oporation can now be practised expeditiously because it is no longer necessary to get into the rand crease or to the extreme top edge 76 of the heel. If this operation results in the production of a ridge due to overla ping rush strokes, such a ridge may be e seed, for example, by heading the heel along its upper ed e at the point where the overlap- 80 ping stro es occurred.

The first step of this 0 oration may pr'eferably be effected b utilizing the machine which forms the su ject-matter of my copendin application Serial No. 202,143 filed Novem or 15, 1917. A feature of the invention consists in rotating a blocking applying member in engagement with the rand crease in order to insure the thorou h application of blocking to the crease an thereby sub-'90 stantiallysimultaneously to 0 en said crease and beat down the upper sur ace of the sole or heel, and in a plying blocking to a portion of the face of the heel or edge of the sole by means of a single movement relatively toa stationary member'in order to avoid brush marks or the like such as might result from a plurality of strokes.

This and other features of the invention will be more readily understood from a consideration of the following specificat' taken in connection with the accompanying drawings, in which,-

Figure 1 is a. plan view of a machinlby means of which the first step of. my novel method may be conveniently carried out;

Fig. 2 shows the application of a shoe to this machine in order to carry out the first step of the method;

Fig. 3shows how the second step of the method may be carried out; and

Figv 4 illustrates the completion of the operation.

One form of machine by means of which the first step of my novel method may carried out is illustrated in Fig. 1 and will be seen to comprise a main power shaft 10 connected by worm gears to a jack shaft 12 supporting a disk 14 which dips in blacking contained in a tank 16 and which delivers the same to one face of the concave disk constituting the rand crease guide 20. This guide 20 is positively driven by means of a gear connection to the shaft 12 and 1s arran (1 to rotate in a counter-clockwise direction as viewed from the concave side of the disk. The convex side of the disk is blacking to the rand crease .26 is supported in a )Fig. 3. The term rand cleaned by means of a wiper 22 of usual form so that no blacking will be applied to the upper of the shoe when the disk is inserted in the rand crease.

Mounted beside the disk and in frictional engagement with a portion of the periphery thereof is a soft bristle brush 24 whose shaft bracket 28 adjustably held upon the frame by means of a bolt 30. The upper end of the bracket is slotted at 32 to allow backward and forward adjustment of the bracket and its brush shaft 26, this movement being restricted to a straight line by co-aeting faces 29 on the bracket and the frame, and the shaft 26 may be lon itudinally adjusted within the bracket by oosening a set screw passing through a collar 32 between two arms of the lower end of the bracket. Upon this collar are ratchet teeth 34 which cooperate with a pawl 36 upon the bracket. s will be seen by an inspection of the drawing the brush is undriven and is arranged for free rotation in the same direction as vthe disk but is held stationary upon the application of the work which is commonly moved upwardly against the motion of the disk.

The preferred method of blacking a heel in accordance with my invention is to apply 40 and a portion of the adjacent face of the heel 42 or edge of the sole'in one operation, as indicated in Fig. 2, and to black the remainder of the heel in another operation, as indicated in crease is used generically herein to indicate any part of the by means of a heading w crease between the uppgr and the sole. indications of a joint tween the two applications of blacking ma then be effaced, for e mple, by beading t e upper edge of the h el m the usual manner, as for example,

heel 60 such as shown in Fig. 4. In practising this method upon the improved machine just described, the work will first beheld in the position indicated in Fig. 2 and will then be moved upwardly past the relatively stationary brush and the disk against the direction of rotation of the disk and, being turned, blackbut will at the same time open up the crease where it may have become partially closed" during the operation of heel trimming or heel scouring and will also beat down the upper edge of the sole or heel and eliminate any rough edges or loose fibers. After an application of the work to the machine, the brush will be carried forward in a counterclockwise direction by reason of the fric tional engagement between the guide 20 and the brushsand blacking will be delivered to that portion of the brush which is advancing into-position for engagement with the work, it being somewhat retardedby the brush and piled up, thereby to fill the brush.

The remainder of the face of the heel may then be blacked, according to the second step of my method, in any desired fashion as, for example, by the manual application of blacking with a single stroke of a camels hair brush (see Fig. 3). Inasmuch as the upper edge of the face of the heel has already been blacked it is no longer essential that this manual operation be carried over the extreme width of the heel and conw quently it may be effected much more quickly and accurately. Any possible rid 0 (see Fig. 3) which may be formed by the overlapping strokes of the two applications of blacking will, according to the third step of my method, be efi'accd when the heel 1s beaded in the usual manner by means of a wheel such as shown in Fig. 4.

Having thus described my invention, what I claim as new and desire, to secure by Letters Patent is:

1. The method of blacking a heel which consists in applying blacking to a portion of the face of the eel or edge of the sole adjacent-to the upper in one operation, applying blacking to the remainder of the heel in another operation, and efiacing any indications of the joint between the two a plications.

2. he method of blacking a heel which ing to the rand crease in one operation, and applying blacking to the face of the heel in another operation.

3. The method of blacking a heel which consists in applying blacking to the upper 130 p of the face consists in opening up and applying blackportion of the face of the heel or edge of the sole and beating the upper edge of the sole or,heel in one operation, a plying blacking to tharemainder of the bee in another operat1on,'-and beading the heel along the oint between the two applications to efi'ace any indiatioiis of a oint.

hmhemetho of blacking a heel which consists in opening up and applying a coat of black-in'g to the rand crease and adjacent edge of the heel or sole in one 0 eration, and applying a coat of blacking to t e remainder o the heel in another operation so that it slightly overlaps the coat'applied to the top edge of the has or sole.

5. The method of blacking a heel which consists in applying a coat of blacking to the rand crease and adjacent edge of the heel or sole and beating the upper edge of the sole or heel in one operation, applying a coat of blacking to the remainder of the heel in another operation so that it slightly overlaps the coat applied to the top edge of the heel or sole, and efiacing the marks of overlapping by beading said top edge of the heel or sole.

6. The method of blacking a heel which consists in a plying blankingl to the rand crease and a Lament edge of t e sole or heel by moving t e work along a guide and against a relatively stationary blacking app ying mengilben'and applying blacking to the remainder of the face of the heel b holding the work relatively stationary an drawin a blackingl applying device around the sur ace of the ee 7. The method of blacking a heel which consists in a plying blackingl to the rand crease and a Lacent edge of t e sole or heel by moving t e work along a guide and ainst a relatively stationary, blacking app yin member, applying blackin to the remain er of the face of the heel g holding the work relatively stationary an drawing a blacking device around the surface of the heel and efi'acing any indications ofthe joint between the two a plications of blacking by beading the top e ge of the heel or sole.

8. The method of blackin a heel which consists in rotating a blac ng a plyingmember in engagement with the ran crease to insure the t orough application of blacking to the crease, afp illying blacking to a portion of the face 0 t e heel or edge of the sole by means of a single movement relatively to a stationary member so that there will be no brush streaks as from a plurality of strokes, and applying blacking to the remainder of thn iace of the heel in an operation separate 0m said first-named applications.

In testimony whereof I name to this. s ecification.
